TYPES: AUSTRALIA: Queensland: Male holotype, female allotype, and one female paratype from Hinchinbrook Island, Macushla Cove , 18.22666 ° S, 146.21777 ° E (3 May 2009, K. Edward and P. Cullen), deposited in QM (³ holotype: QM S95995 View Materials , PBI _ OON 00005641; ♀ allotype and paratype: QM S95996 View Materials , PBI _ OON 00005642) GoogleMaps   .

ETYMOLOGY: The specific epithet is a patronym in honor of Robert J. Raven of the Queensland Museum (Brisbane), in recognition of his enormous contribution to taxonomy and collections of Queensland spiders.

DIAGNOSIS: Males of this species can be distinguished by the slight bifurcated distal tip of the obtusely bent embolic region of the palp (fig. 65A–D) and the fang basal process, which has small ridges on the anterior aspect (fig. 65C). Convoluted duct of the female epigynum becoming thinner posteriorly and ending at a darkened circle. The process overhanging the epigynal atrium is heavily sclerotized, broad, and relatively straight with a very slight medial indent (figs. 64I, 65F).

MALE (PBI_OON 5641, figs. 64A–C, G– H, 65A–E). Total length 1.75. CEPHALO- THORAX: Carapace pale orange, broadly oval in dorsal view, pars cephalica strongly elevated in lateral view, anteriorly narrowed to between 0.5 and 0.75 times its maximum width, anterolateral corners without extension or projections, surface of elevated portion of pars cephalica finely reticulate, sides finely reticulate. Clypeus margin unmodified, curved downward in front view, high, ALE separated from edge of carapace by their radius or more; setae dark. Eyes: ALE largest, ALE circular, PME circular, PLE oval; posterior eye row procurved from above; ALE touching, ALE-PLE touching. Sternum longer than wide, pale orange, uniform; setae dark, evenly scattered. Chelicerae, endites, and labium pale orange. Chelicerae straight, anterior face unmodified; promargin with one larger denticle; fang shape normal, with prominent basal process, small ridges on anterior aspect of basal process; setae dark. Labium elongated hexagon, not fused to sternum, anterior margin indented at middle, same as sternum in sclerotization; with six or more setae on anterior margin. Endites anteromedian tip with one strong, toothlike projection, same as sternum in sclerotization. ABDOMEN: Cylindrical; dorsum soft portions white. Book lung covers elliptical. Dorsal scutum pale orange, covering more than 3/4 of abdomen, more than 1/2 to most of abdomen width, middle surface smooth, sides smooth. Epigastric scutum small lateral sclerites present. Postepigastric scutum pale orange, covering about 1/2 of abdominal length. Dorsum, epigastric area, and postepigastric area setae dark. LEGS: Pale orange, without color pattern; patella plus tibia I shorter than carapace. Leg spination: femora: I p0- 2-1; II p0-1-0; tibiae: I, II p2-2-0; v2-2-0; metatarsi: I, II p1-1-0; v1-1-0. GENITA- LIA: Palp proximal segments dark redbrown; embolus dark; femur shorter than trochanter; patella about as long as femur; cymbium dark red-brown; bulb dark redbrown, more than 2 times as long as cymbium, stout; embolic region elongate, obtusely bent, curved distally toward prolateral

aspect, distal tip slightly bifurcated (figs. 4H, 65A, B).

FEMALE (PBI_OON 5642, figs. 64D–F, I, 65F). Total length 2.20. CEPHALOTHORAX: Carapace pars cephalica slightly elevated in

lateral view, anteriorly narrowed to 0.49 times its maximum width or less. Clypeus low, ALE separated from edge of carapace by less than their radius. ABDOMEN: Ovoid. Dorsal scutum covering 1/2 to 3/4 of abdomen, between 1/4 and 1/2 abdomen width. Postepigastric scutum widely hexagonal, only around epigastric furrow. LEGS: Leg spination: femora: I p0-2-1; II p0-1-0; tibiae: I, II p2-2-0; v2-2-0; metatarsi: I, II p1-1-0; v1-1-0. GENITALIA: Ventral view: strong horizontal sclerotization anterior to rounded epigynal atrium, thick, clearly joins posteriorly direct- ed lateral apodemes; heavily sclerotized process overhanging epigynal atrium mostly with straight edge, slight medial indent; convoluted duct much thinner than apodemes in posterior section, widening anteriorly (figs. 64I, 65F).
